After taking into account the particular site conditions, subterranean groundwater treatment, which removes without residues iron, manganese, also arsenic and ammonia, is an economically attractive alternative to conventional processes in planning and operation. Biological mechanisms play a key part in subterranean groundwater treatment. Research still remains to be done to explain these mechanisms and optimize the process.
